Giant planets are separated into 4 categories. Giant planets of the Solar System show weak irradiation and interior flux and rapid rotation. Hot Jupiters are known for strong irradiation, weak interior flux and moderate rotation. Field Brown Dwarfs and directly imaged giant planets have negligible irradiation, strong interior flux and fast rotation. Finally, irradiated brown dwarfs display strong irradiation and interior flux, and modest to rapid rotation. Understanding the atmospheric circulation and thermal structure of giant planets requires investigating these 4 categories.

In this talk, we will discuss the latest development of the generic Planetary Climate Model for the study of the atmosphere of hot giant gaseous objects.

First, we will discuss the traditional case of a Hot Jupiter in synchronous rotation around its star, WASP-43b. We will discuss the dynamical and thermal structure and the cloud distribution of such objects. We will show that clouds are mandatory to explain the HST-Spitzer and MIRI phase curves.

Secondly, we will discuss our ongoing work on the impact of eccentricity and clouds on the thermal and dynamical structure of Hot Jupiters, as ~ 20% of detected Hot Jupiters display non-circular orbits. 

These studies focus on the strong irradiation and moderate rotation with weak interio flux regime. We will then present our preliminary results on the adaptation of the generic PCM to the case of field brown dwarfs around the L/T transition. We will especially focus on the cloud distribution as a function of the effective temperature and discuss the observational consequences for such objects.
